HClrRBit

You can use the HClrRBit procedure to clear the resource flag of a relocatable block. The Resource Manager uses this routine extensively, but you probably won't need
to use it.

PROCEDURE HClrRBit (h: Handle);

h

A handle to a relocatable block.

DESCRIPTION

The HClrRBit procedure clears the resource flag of a relocatable block. It does nothing if the flag is already cleared.

ASSEMBLY-LANGUAGE INFORMATION

The registers on entry and exit for HClrRBit are

Registers on entry
A0	Handle whose resource flag you want to clear

Registers on exit
D0	Result code

RESULT CODES

noErr	0	No error

SEE ALSO

To disassociate the data in a resource handle from the resource file, you should use the Resource Manager procedure DetachResource instead of this procedure.
